checkpatch: make the CamelCase cache work for non-git trees too 

Might as well check include timestamps and cache the include file
CamelCase uses for the non-git case too.

The camelcase cache file is now named:

  for git:      .checkpatch-camelcase.git.<commit_id>
  for non-git:  .checkpatch-camelcase.date.<YYYYMMDDhhmm>

All .checkpatch-camelcase* files are deleted if not current.
